Abstract:By combining pumpedstorage power station and hybrid wind/PV system,hybrid wind/PV/pumpedstorage system was established,in which wind power model was achieved by manufacturer provided linear interpolating characteristic curve,PV modeled by Hay model,charging model and discharging model for battery as well as pump condition and turbine condition for reversible pump turbinewere modeled,respectively. Using VC 2008,an userfriendly simulation software was developed,which can simulate the output power of wind turbine,PV,reversible pump turbine and AC/DC loads.By an example the following were achieved. Firstly,as the total power of wind and PV was less than the total loads,the reversible pump turbine operated in turbine mode to generate power for loads. In the several hours of higher light intensity and higher wind speed,the total power of wind and PV was more than the total loads,and the reversible pumpturbine operated in pump mode to pump water to store the extra power energy in the form of water potential energy.Secondly,normally batteries were at the state of full capacity,just as loads were very instant or were very large,the batteries discharged and after discharging they could be recharged immediately.
